In view of the Rosenberg problem and the projection pursuit theory on statistics,the paper structures the density function f(x) of the n dimensional non normal population.

鉴于Ｒｏｓｅｎｂｅｒｇ问题及统计中的投影寻踪理论，构造了非正态的ｎ维总体密度函数ｆ（ｘ），且其在ｌ（１≤ｌ≤ｎ）维超平面Ｌｉ上的投影密度ｆｉ（Ｚ）为正态密度，其中，１≤ｉ≤Ｎ（Ｎ为任意有限数），当ｉ≠ｊ，１≤ｉ，ｊ≤Ｎ时，Ｌｉ≠Ｌｊ。

This paper defines the normality of setvalued random variable,gives its representation,and describes its relationship with usual random variable.

从集值随机变量的定义出发,利用嵌入函数这个工具,给出了集值随机变量正态的定义,并且给出了它的一个表示,揭示了它与一般的随机变量正态的关系。
